I need the configure file to transpile from C++ to JS, I'm trying to use emscripten in a project. Emscripten comes with a tool called emconfigure, that replaces the autoconf configure,
But the project I'm building uses cmake as build system and currently (Jan-12) emscripten has only support for autoconf - so I'm bypassing it by generating the configure and doing a port on the make, so there a way to create the configure file from the cmake ?? I'm not talking about the make files.. but the configure file itself.
Yes, it can:
configure_file(<input> <output>
[COPYONLY] [ESCAPE_QUOTES] [@ONLY]
[NEWLINE_STYLE [UNIX|DOS|WIN32|LF|CRLF] ])
Example.h.in
#ifndef EXAMPLE_H
#define EXAMPLE_H
/*
* These values are automatically set according to their cmake variables.
*/
#define EXAMPLE "${EXAMPLE}"
#define VERSION "${VERSION}"
#define NUMBER ${NUMBER}
#endif /* EXAMPLE_H */
In your cmake file:
set(EXAMPLE "This is an example")
set(VERSION "1.0")
set(NUMBER 3)
configure_file(Example.h.in Example.h)
Configured Example.h
:
#ifndef EXAMPLE_H
#define EXAMPLE_H
/*
* These values are automatically set according to their cmake variables.
*/
#define EXAMPLE "This is an example"
#define VERSION "1.0"
#define NUMBER 3
#endif /* EXAMPLE_H */
